Ghana midfielder Bernard Mensah has arrived in the Turkish capital Istanbul to complete his loan move to Besiktas.
The 25-year-old left Kayseri on Sunday evening and will complete his loan move today.
Mensah will undergo a mandatory medical test today before sealing the transfer deal.
He will sign a 500,000 Euros loan deal with Besiktas on Monday if he passes the medical.
Before travelling to Istanbul he signed a one-year extension to his contract with Kayserispor who now have him under contract until 2022.
Beşiktaş will have the first option to buy Mensah for 4.5 million Euros at the end of the season.
Mensah was on a buyout clause of 2.8million Euros at Kayserispor at the beginning of last season before his latest contract extension scored 5 goals and 8 assists in 26 matches.
